Suggested Answers:

a. Importance and

Characteristica of Dairy Farming in New Zealand

1. Dairy cattle rearing is an important agricu) tural } activity of New Zealand. New Zealand is the world's biggest and most efficient export of dairy products. The industry has developed an account of the increasing demands from cities for milk, cream, butter and cheese,

2. The dairy industry in

New Zealand contributes almost a third of the total value of the country,

3. Dairying in New Zealand is

solely on a commercial scale.

4. About 75% of New Zealand

farms are found in North Island, on the SW and NE lowlands.

5. The size of an average

dairy farm is about 60 -80 hectarea, and grazes

a dairy herd of around 100 cattle. However, since the past 15 years, the trend has been changing in favour of large farme,

The main breed of cattle To the Jersey which is i noted for the high yield of butter fat in the milk, but the Friesian is going in popularity because of the current trend in dairy farming towards combining dairy production with beef production.

7. The operation of the farm is highly mechanised, with electric fences, electric milking machines and highly automated milking sheds and collecting yards,

8. The industry is organised

along highly efficient cooperative linsa, The farmers within a particular area have their milk collected daily by tankára to the dairy faétories, where milk in touted, pasteurised and proesungd,

b. Favourable Conditiona

Leading to the SucceAA Physical Conditions:

1. New Zealand enjoys

warm temperate oceanip climate. Winters are mild which permit outdoor grazing throughout the year.

2. The mild, moist climate

and fertilized soil allow the growth of excellent grass and hay crops like alfalfa,

:

3. It has cool surime r

temperaturen. Dairy cattle give much milk in conl summers and milk can be kept for a longer period,

4. It has low rolling and

humid plaina.

networks to connect the chief pastoral areas the Waikaito Valley, Taranki Lowlands and Hawke's Bay --- to the main population centres, 0.g. Hamilton, Auckland and Wellington.

2. Oversea markets are also

favourable, New Zealand used to get a preferential tariff from the United

Kingdom. Though this

contract had ended

recently, sales to SE Asian countries are still optimistic,

3. The invention of

refrigeration enables the dairy products to he exported over long distance without going bed.

4. The early settlers are

hardworking and open-minded, they are enger to seek new ideas, try out new techniques an and carry out researches, 5. Pastures are improved by using superphosphate. Quality of dairy products is raised by introducing better breeding of cattle, e.g. crossed breed of the Jersey and Friesian,

6. The innovation of milk

tanker makes transporta- tion of milk efficient. It has encouraged the growth of multi-plants and multi-production companies (which process butter, cheese, and milk powder all under one roof) and at the same time, lowers the cost of production.

7. There are organized

cooperatives to market the dairy products.

8. The dairy industry is

greatly aided by the New Zealand Dairy Board, too. The Board is responsible for the co-ordination of dairy processing and marketing, It helps to inspect the products carefully and guarantees the quality, It also carries out researches so na to provide technical services and advices.

44. Below are descriptions of

the forests in Indonesia and New Zealand;

"About 2/3 of Indonesia is under forest, yet only 3% of the total forested areas is under commercial exploitation."

"At the early period of New Zealand's development forested land blanketed about 70% of the total land aren, Yet after a hundred years and more, forented regions only amount to 23.2% of the total area in 1965,"

*. Explain why so little

timber resource has been exploited in Indonesia while in New Zealand it in rapidly exhausted.

b. What measures have been

undertaken by the two governments for any bettermenta?

Suggested Answera;

a. Reasons for the Small

Exploitation of Foreat Resources in Indonesia.

are

The rich timber regource has been exploited very little because the trees usually of mixed stands, making it difficult for selection. The thick under- growth, the dense growth of elishing plants and parasites and poor communications make there forests difficult to penetrate or eveu

inaccessible. The hard wond is also difficult to fell. Since population 18 sparse and diseases and insects are widespread in this region, little labour is available. Moreover, in this primitive area, due to the lack of capital, only very low level of technology and peor technique are employed. Systematic development of this area is late because of the insular nature of the country, exploitation is limited to a few islands only.

Reasons for the Rapid Exhaust of Forest in New Zealand

The rapid decrease in forest resources in New Zealand is partly due to the commercial exploitation during the Colonization of the European settlers, Lumbering is highly developed there since it is mainly temperate coniferous forest, The coniferous trees are soft wood, the trunks are tall, slender and thin, therefore, they can be felled easily. The usages of the trees and the demand for them are high too, such as pulp and paper making and construction. Besides this, the rapid exhaustion is also due to the careless burning of the Maories, the damage caused by volcanic eruptions and the need for clearing for the expansion of agricultural and pastoral Activities.

Measures Undertaken by the Indonesia Government

The 5-year plan and the 10-year development programme set targets for the expansion of timber production. There are schemes to survey and exploit forestä, and to research and investigate into forest potentiala, e.g. for making rayon, paper, tanning, plywood and synthetic fibres,

The Forest Inventory and Land Development Centres have been set up by the Indonesian Government. They take up the responsibility to plant various species and carry out the work of referentation for industrial use and to control felling of trees. These work are helped by improved communications.

The government also encourages overseas investment and introduces numerous improved technology.

Measures Undertaken by the Government of New Zealand

The New Zealand's Government has been keenly aware of the deficiency in timber production resulted from the indiscriminato felling which leads to domestic timber shortages. Remedial measures focusing on reforestation and conser- vation of forest resources are being enforced. The New Zealand Forest Service, which includes the Forest Hesearch Institute and a staff training centre et Rotorua, waa ratablishad in 1919. It is responsible for conservation of both natural and exotic forests, increase of foreat resources and control and noxious animals.
